Has to be Oscar De La Hoya

Vs Trinidad- Still crying until today about that match, was caught crying on camera like a baby after the fight while punching the lockers.
Vs Mosley 1- The press conference after the fight he claimed boxing was corrupt and that he really won a fight that was fixed, even thought he stated in the ring that Shane won the fight when talking to Larry Merchant
Vs Mosley 2- Claimed he would appeal the fight to the boxing council

Notice he never said anything about fights that he lost but recieved the victory (Quartey, Whitaker, Sturm). No appeal to the boxing council about those
